Hi,
We can only help you getting the spawner back if you was due to the a bug! So are you sure it
• didn’t fall in the void when mining it close to an edge.
• wasn’t left on the ground for longer than 5 min (natural despawning time)
• you threw it away (most likely not but just checking)
•...
If you’re sure you lost it because of a bug I’ll tell the appropriate staff member to come and take a look at your situation.
If not, then I’m sorry and we can’t give it back. You’ll need to buy a new one in this case...
Make sure to include you Gamer Tag/username already if you lost cause a bug ^-^
